Australian Sea Lion Foraging Habitat from Bio-logging Instruments

Data from eight adult female Australian sea lions instrumented with bio-logging devices during single foraging trips. Video, GPS, time-depth, and accelerometer/magnetometer data was collected from individuals at Olive Island and Seal Bay in South Australia. This project by the Australian Ocean Data Network provides information on critical benthic habitats and foraging behavior to support conservation actions.

Use Cases

• Map critical benthic habitats for sea lions based on GPS and video data mentioned in the description
• Analyze individual foraging behavior differences based on time-depth and accelerometer data mentioned in the description
• Identify prey preferences and assess ecological value of habitats based on video imagery mentioned in the description
• Model population risks and inform conservation strategies based on identified habitat use patterns

Strengths

• Includes data from eight instrumented animals, providing individual-level behavioral records
• Integrates multiple sensor types: video, GPS, time-depth recorders, and accelerometer/magnetometers
• Covers two distinct geographic locations: Olive Island on the Eyre Peninsula and Seal Bay on Kangaroo Island

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the two specific study sites
